Could you help me with Czkawk4? I clicked on "select the smallest file" and started going through the files one by one, manually unchecking the ones I wanted to keep. But when I noticed the time, I had to leave, and I realized I wasn't even halfway through. I want to know how to unselect everything else. Because when I select "mark all the smallest files," I don't know how to unselect the other half. Do you recommend any other program? Because I've noticed that the program doesn't recognize four images where the character has a different skin tone as "the same."
